What if the asteroid that decimated the dinosaurs missed the earth by a whisker? That's what the trailer of Pixar's new film The Good Dinosaur seems to be asking.

What if the asteroid that decimated the dinosaurs missed the earth by a whisker? What if dinosaurs continued to thrive and met humans somewhere down the line on the evolution highway?

That's the premise of Pixar's long-delayed film The Good Dinosaur. A minute-long trailer of the film has proved that the film has put its production troubles behind it and is finally ready for release.

Going by the visually-vibrant trailer, the film is about dinosaurs of every kind inhabiting the earth. Director Pete Sohn's film is about an Apatosaurus named Arlo who gets separated from his pack and meets a boy whom he names Spot.

The film from there is a boy-meets-dog story where dino is the boy and human is the dog. As Arlo tries to find his way back home, we see Spot as almost feral. Sohn has said in a recent interview, "Arlo himself is what we would have become, able to articulate and have certain emotions and connection to family. They've become us, essentially… I'm trying to treat Spot in a very kind of animalistic way, where he doesn't speak very much. He's very feral."

The film does not strictly keep to the human evolution timeline, but seems to tell an interesting story. The film releases in November this year.
